Scientists, speak up! Source impacts trust in health advice across five countries.

We examined how different types of communication influence people's responses to health advice. We tested whether presenting COVID-19 prevention advice (e.g., washing hands/distancing) as either originating from a government or scientific source would affect people's trust in and intentions to comply with the advice. We also manipulated uncertainty in communicating the advice effectiveness. To achieve this, we conducted an experiment using large samples of participants (N = 4,561) from the United Kingdom, the United States, Canada, Malaysia, and Taiwan. Across countries, participants found messages more trustworthy when the purported source was science rather than the government. This effect was moderated by political orientation in all countries except for Canada, while religiosity moderated the source effect in the United States. Although source did not directly affect intentions to act upon the advice, we found an indirect effect via trust, such that a more trusted source (i.e., science) was predictive of higher intentions to comply. However, the uncertainty manipulation was not effective. Together, our findings suggest that despite prominence of science skepticism in public discourse, people trust scientists more than governments when it comes to practical health advice. It is therefore beneficial to communicate health messages by stressing their scientific bases. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The Progressive Values Scale: Assessing the Ideological Schism on the Left.

Progressivism has increasingly challenged traditional liberalism as the dominant influence within left-wing ideology. Across four studies, we developed a measure-the Progressive Values Scale (PVS)-that characterizes distinctly progressive values within the left-wing. In Study 1, left-wing participants evaluated divisive issues, with four scale factors emerging. In Study 2, we confirmed this factor structure and included a battery of personality and values measures to explore individual differences among those who maintain a progressive worldview. In Study 3, we achieved final confirmation of the factor structure and validated the ability of the PVS to assess a distinctly progressive perspective, insofar as progressives generated prototypical faces for Liberals and Conservatives that were markedly distinct from those generated by traditional liberals. In Study 4, we distinguished the PVS from measures of left-wing authoritarianism and demonstrated that it is a better predictor of progressive political preferences and social judgments.

Spirituality is associated with Covid-19 vaccination scepticism.

Vaccine scepticism poses a significant global health risk, which has again become clear during the ongoing Covid-19 pandemic. Previous research has identified spirituality as an important contributor to general vaccine scepticism. In the present manuscript, we assessed whether self-identified spirituality similarly contributes to scepticism towards Covid-19 vaccines, vaccine uptake, and indecisiveness in intention to be vaccinated. We conducted three studies online in the UK in late 2020, early 2021, and the summer 2021. In Studies 1 and 2 (N = 585), as expected, individuals who strongly identified as spiritual were more sceptical about Covid-19 vaccines. This association was explained by low faith in science, but not by conspiracy beliefs. Importantly, among the vaccinated participants, those who were more spiritual were more indecisive to get a Covid-19 vaccine. Using structural equation modelling (SEM), we further found that spirituality directly predicted lower likelihood of being vaccinated against Covid-19 (Study 3, N = 456). We also identified low science literacy as an additional predictor of Covid-19 scepticism, but not self-reported vaccine uptake. To conclude, spiritual beliefs are an important factor to consider when aiming to increase understanding of vaccine-related science scepticism and vaccination rejection.

Science rejection in Greece: Spirituality predicts vaccine scepticism and low faith in science in a Greek sample.

Recent research has identified spirituality as an important contributor to vaccine scepticism and low faith in science, particularly in WEIRD (Western, Educated, Industrialized, Rich and Democratic) nations. In the present study, we further tested the generalizability of these findings in a religious South-Eastern European country - Greece, with more extensive measures of key constructs. We replicate previous work using measures of improved construct validity. Spirituality was found to be the strongest predictor of vaccine scepticism and low faith in science. In addition, low science literacy was also predictive of vaccine rejection. Climate change scepticism was not associated with spirituality but with political conservatism, which corroborates previous findings. These results provide further evidence for two previously made observations: science scepticism is heterogeneous, and spirituality is an important factor in shaping science rejection.

Powerful men on top: Stereotypes interact with metaphors in social categorizations.

We examined whether people can simultaneously apply 2 cognitive strategies in social categorizations. Specifically, we tested whether stereotypes concerning social power of gender categories interact with metaphoric power-space links. Based on the conceptual blending perspective suggesting that semantically consistent concepts acquire each other's properties, we predicted the following: Given that stereotypes create expectations linking gender with power, and metaphorically power is linked with vertical space, the conceptual blend of gender-power-space would invoke representations of male targets at the top vertical position when categorizing them as powerful, while female targets at the bottom when categorizing them as powerless. Across 6 studies, we show that the concept of gender is simulated spatially when people attribute power to male, but not female, targets. The predicted power-gender blending involved simulations of men judged as powerful when presented in upper location as opposed to women judged as powerful in upper location and men judged as powerful in lower location. Our hypothesis was further corroborated using pupillometry to assess preconscious processing, whereby stereotypically inconsistent orientations of gender and power evoked pupillary markers indicative of surprise. Our studies suggest that gender-power stereotypic expectations interact with the power-space metaphor in social categorizations. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
